Chemical Structure

Fumaric Acid-1,4- CAS 96503-56-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fumaric Acid-1,4-.

Fumaric Acid-1,4- (CAS 96503-56-9) is a high-purity analytical reference standard with the molecular formula C2[13C]2H4O4 and a molecular weight of 118.06 g/mol.

Fumaric Acid-1,4- (C2[13C]2H4O4) contains a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
